Ruoye, a genius college student known as the "most powerful brain in mankind", was reincarnated into a different world after his accidental death and became the strongest Nether Dragon Emperor in the other world. After breaking through the seal, he was extremely weak. In order to survive, he signed a life-and-death contract with the dying slave girl, a magic spell, and became a lifelong and eternal reincarnation partner.
What kind of sparks will fly between the strongest Dragon King and the weakest girl?
